Application filed March 23, 1925, Serial No. 17,668.

My invention relates to improvements 'in snubbers for antomobiles,' or similar vehicles.

The objects of my improvements are; first, to provide a snubber simple in construct1on,

positive in action and made withfew partsi Second, to provide the required resistance for snubbing by combining frictional resis-- tance and a rotary coil spring 'CGIlSlOnIQSlS I tance. Third, to provide a cushion against sudden jerks from the snubbing strap in order to prevent the breakingof straps.

I attain these objectsby the Inechanisni illustrated in'the accompanying drawing in which;

Fig. 1 is a cross section of the general assembly.in a normal position. Figp2is a the frame of an automobile.

front view showing methods ofconnection to Fig. 3 shows the snubber coil in a contracted position and snubbing web drawn out. Fig. ,4 is apart elevation and section of'the rear side, showing the connections to link.

Similar numeralsrefer to similar parts, thruout the several views. n

The part 1 constitutes the fixed hub se curely anchored to the automobile frame 8 and casing 5; said hub is'held firmly in a rigid position and serves as a basefor limiting thecontraction of the coil spring 2. v

The helical flat coil spring 2 is hooked into'l at the fixed end as shown and the other end is freeto move in an arc and isconnected to link 4. The non-combustible fibrous web 3 is attached to axle 9 ofan automobile and fastened with clamp 10 and thence extends aronnd the flat coil springQ, in cylindrical contact with said spring to a pointer where it terminates and connects to link 4. Link 4 pivotally connects the end of snubbing web '3 at a and the free end of coil spring 2 at b so'that when the-coil contracts it permits the web to slip on the surface of the coil, thus combining frictional resistance and spring tension for the required resistance of the snubbing web.

of the coil The housing 5 completely encloses thecoil 2 substantially as shown. Bolt 7 securely fastens the snubbing device to the automobile frame '8 and the lug 6 prevents rotation hub lby its abutting contact with frame 8. a a V In operation," the webS is drawn downwardly and the coil spring 2 contractedin arotary direction to'a typical point as shown in Fig. 8'; in the same operation the'webloing 3 slideson the surface of the coil spring '2 producing frictional resistanceiin addition to the spring tension resistancefrom the "coil spring transferred to the webv by means of link 4. As the stress on the web by the axle is reduced, thecoil expands and draws the web back to-its normal-position at a Fig. 1.

The total length of travel for the web 3 is obtained by the unwinding of the web from the coil spring from positionB, Fig. 3 to position B, Fig. lhplus' the slipping of webbing on the coil from position A, Fig. 1 to position A, Fig. 3. Thus in this simple manner it is possible to get greater travel for the webbing, with less webbing and a shorter and stiffer coil than is possible ifno sliding provision were provided. The positionfo'f the various partsshown in the contracted view Fig.3 are only-typical and I therefore Q do not confine myself t0 thev specificillug tration as shown. v r

I am aware thatsnubbers are on the mar- I ket, but notzto my knowledge is my combina- I .l

tion used and I'thereforeclaim as follows:

. The combination in an automobile snubber, of ar fiatcoil 'spring,fone,end in fixed 7 position, the other endfree to move in a rotating dlrection, a 11011-COI1lb1lSl3lble"fl10- tional web slida'bly mounted on the external cylindricalsurface of a portion of said coil, one end of, said web extended and connected to the axle of thevehicle snubbed, the other end connected by a link to the free end of 7 said coil spring, all substantially as set forth.
